# Delx Seeded UUID Generator

> Delx Seeded UUID Generator is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Generates a deterministic UUID v5-style value from a name, seed, and namespace, returning the same UUID every time the same inputs are supplied.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/seeded-uuid
- Price: $0.001/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-seeded-uuid-generator-ca117eb1 -d '<json body>'
```

Example prompt: Generate a deterministic UUID using the name 'invoice-2024', seed 'acme-corp', and namespace 'billing' — I need the same UUID every time I pass those exact values.

## When to prefer this

Choose this endpoint when you need a UUID that is reproducible given the same inputs — for idempotent resource creation, deduplication, content-addressed identifiers, or stable primary keys across agent runs. Prefer it over random UUID generation when consistency across retries or environments is required, and over local UUID libraries when you need an auditable, server-confirmed result with an input hash for traceability.

## Known failure modes

- Missing required fields (name, seed, namespace) may return a validation error
- Inputs exceeding 8192 characters per field may be rejected
- Network or payment authorization failure returns a 402 or 5xx error
- Malformed JSON body returns a 400 error

## How this service works

Seeded UUID: Seeded UUID derives a reproducible UUID-shaped identifier from seed and namespace text from bounded caller-supplied values without an external provider. Call Seeded UUID when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded UUID as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-…

## Output

Returns a JSON object containing a deterministic UUID string (e.g. 'c3697cf7-7902-53aa-b2e5-7933db6068e2'), a boolean confirming determinism, an SHA-256 hash of the input for audit purposes, confirmation that zero external calls were made, and a status of 'pass'.
